Chemical Structure
Description
The occurrence of 2-Bromo-7-fluoro-1H-benzo[d]imidazole is closely related to a nitrile group, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Bromo-7-fluoro-1H-benzo[d]imidazole (CAS 1379327-75-9), a certified reference material (molecular formula C7H4BrFN2, MW 215.02 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-7-fluoro-1H-benzo[d]imidazole (C7H4BrFN2) is characterized by a nitrile group, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
